Specification of Letters Patent.

To all whom it may concern:

Be it known that I, WVILLIAM H. OSBORN, a citizen of the United States, residing at Oakdale, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvement in ater-Closets, of which the following is a specification.

The object of my contrivance is to provide apparatus for automatically flushing waterclosets direct from the supply-pipe and without the use of a tank, affording at the same time means for regulating the length and amount of flushing and preventing leakage at the entry into the bowl or flushing-rim. I attain these objects by means of the mechanism illustrated in the drawing, in which the figure is a vertical sectional elevation of a portion of the closet-bowl and my improved system of valves applied thereto.

A is a lug or lever attached to the hinged closet-seat projecting downward into the bowl and actuating rearward a spindle B, to which I prefer to attach adjacent to the lever the friction wheel C to prevent binding, and which spindle is guided truly along and within the tube M, hereinafter described. The spindle bears a valve-disk D and after an interval of some inches a valve-disk E, a spring F, adapted to actuate the spindle forward, and to the front of disk D the spiral spring N. These disks are rigidly attached to the spindle and are composed of rubber or like soft material or are faced with such material, so as to make a waterproof joint with slight pressure. The spindle is normally actuated forward by the springs acting on the shoulders or valve-seats within said tube, and thereby the spindle is normally pushed upward. \Vhen the spindle is thus actuated forward, the disk E presses against the seat T and closes that aperture in the tube, the valve D S being open. Then the spindle is pushed back, the disk D presses against the seat S and closes that aperture in the tube, the valve E T being open.

Gr is the supply-pipe. This leads into a horizontal tube H, preferably adjacent and parallel to tube M, closed at, both ends and extending in both directions from the entry of said pipe. Into tube H fits a plunger consisting of a central shaft I, bearing near the rear end a disk Q, which fits snugly in the tube, and bearing nearer the front a valvedisk O, adapted to close port P in said tube H when pushed forward, and, further, hearing at the forward ends the guides R R, which fit within the periphery of the tube H where it is narrowerthat is, in front of said port P.

Near the rear end of tube H, which Idesignate as the chamber H, is a pin-hole J, the opening of which is regulated by the pin K, operated by the screw K, which may be readily worked from the outside without disturbing any part of the apparatus. Said pinhole is connected with the supply-pipe, preferably through an auxiliary tube or channel Z. Near the same end of tube H is also aperture L, which leads into the adjacent tube M in the part to the rear of valve E, which I designate as chamber M.

U is a port in tube H, leading into tube M at a point between the two valy e-seats therein.

V is the bowl of the closet, and XV is the flushing-rim.

X is a brass washer actuated by the spring D against the leather washer Y, which forms a water-tight joint between the valve-spindle and the flushing-rim to prevent splashing at the inlet-point from the flushing-pipe to the rim. The washers are rigidly attached to the spindle.

My contrivance operates as follows, being partly the same as shown and claimed in my Patent No. 755,922: \Vhen the closet is out of use, the spindle B is actuated forward by the spring F. The valve D S is thus opened and the valve E T is closed. Consequently the water coming from the supply-pipe through the pin-hole J through the rear part of tube H and through it and aperture L also into the rear of tube M has no exit, and its pressure drives the plunger forward and forces the valve-disk 0 against the valve-seat P, and the water from the supply-pipe is thus shut off from entry into tube M through the valve 0 P. l Vhen the closet is put to use, the weight of the body actuates the spindle rearward, the valve D S is thus closed, and the valve E T is opened. The water back of the plunger-disk Q being thus given an exit, the pressure on that side of the disk is released. The water from the supply-pipe forces this disk Q, back, opening the valve 0 P, and the water flows into and through tube M until its further progress is stopped by the valve-disk D. hen the seat is released, the spindle is actuated forward by the spring F, the valve D S is opened, and the valve E T is closed. The water from the supply-pipe rushes through the valve D S into the flushing-rim. In the meanwhile, the valve ET being closed,the pressure of the water coming through the pin-hole J back of the disk Q, gradually pushes it forward and presses valvedisk 0 against the valve-seat P, whereby the flow of the water through valve 0 P and the tube M into the closet is again entirely cut off. The enlarging or lessening of the pin-hole J by means of the pin K causes the chamber H back of disk Q, to fill with greater or less rapidity, and thus the length of the flushing time may be regulated.

Timing arrangements have been contrived operated by the gradual filling of a tube or chamber with water; but a great advantage of mine is that the tube is arranged horizontally, so that I need no force to counteract the gravity of the plunger and all its movements are more easily effected. What is especially novel and useful about my coutrivance is the combination of the apparatus for timing and regulating the flushing with the valves for doing the flushing operated by the seat and springs.

Having now described my contrivance, what I claim as my invention, and desire to secure by Letters Patent, is-

In water-closets, a spindle, within a tube M, actuated toward the closet by a spring within said tube, and actuated in the reverse direction by means operated by the downward pressure of the closet-seat; a valve-disk D, attached to nearer part of the spindle, which closes a valve D S in tube M when the spindle is actuated rearward from the closet, and a valve-disk E, attached to the farther part of the spindle, which closes a valve E T in tube M, when the spindle is actuated forward; tube H connected with a supply-pipe, and adjacent to tube M; a plunger in said tube H; port P in said tube, and disk 0, connected with the plunger, and adapted to close said port; pinhole J in tube H connected with the supplypipe, and means for regulating the size of said pin-hole; a hole leading from tube H to tube M rearward of valve E T, and a hole leading from tube H to tube M between valve-disks D and E, substantially as described.
